George Monbiot: Imperialism Didn't End ... These Days It's Known As International Law

George Monbiot is the author of the bestselling books The Age of Consent: A Manifesto for a New World Order and Captive State: The Corporate Takeover of Britain.

The conviction of Charles Taylor, the former president of Liberia, is said to have sent an unequivocal message to current leaders: that great office confers no immunity. In fact it sent two messages: if you run a small, weak nation, you may be subject to the full force of international law; if you run a powerful nation, you have nothing to fear.

While anyone with an interest in human rights should welcome the verdict, it reminds us that no one has faced legal consequences for launching the illegal war against Iraq. This fits the Nuremberg tribunal's definition of a "crime of aggression", which it called "the supreme international crime". The charges on which, in an impartial system, George Bush, Tony Blair and their associates should have been investigated are far graver than those for which Taylor was found guilty.

The foreign secretary, William Hague, claims that Taylor's conviction "demonstrates that those who have committed the most serious of crimes can and will be held to account for their actions". But the international criminal court, though it was established 10 years ago, and though the crime of aggression has been recognised in international law since 1945, still has no jurisdiction over "the most serious of crimes". This is because the powerful nations, for obvious reasons, are procrastinating.

Nor have the United Kingdom, the United States and other western nations incorporated the crime of aggression into their own legislation. International law remains an imperial project, in which only the crimes committed by vassal states are punished.
